A man found dead on a road in the Wheatbelt yesterday may have been hit by one or more vehicles, police say.
This morning Major Crash investigators appealed for information over the man's death.
The body of the man, believed to be in his 40s, was found on the Newdegate-Ravensthorpe Road near Newdegate about 6am.
A backpacker travelling to Newdegate discovered the man by the roadside and reported it to police.
Local police attended and cordoned off the area.
Major Crash and forensic officers from Perth travelled to the scene and spent yesterday at the scene.
A vehicle, believed to be linked to the dead man, was found nearby.

"It is believed the deceased man may have been struck by one or more vehicles after his crash," police said. "Officers have since located one vehicle of interest and that vehicle has been seized for forensic examination."
